oilfield drill pipe
oilfield drill pipe
Drill pipe plays a decisive role in the process of drilling, it transfered the drilling torque to drill bit, inordertodrillingunder the well. When it is drilling,drill pipe has complicated load, at the same time it is subjected to stress such as pulling,pressing,torsion and bending, and drill pipe string itself is an elastic system, drilling fluid in the process of drilling and the vibration of the drilling string makes the drill pipe under a great load.
Drill Pipe Type:
E75、X95、G105、S135.

Drill pipe production advantage:
Using the current domestic and foreign advanced heat treatment technology of friction welding deformation, it has small heat affected zone, after welding the stress transition region is more easy to eliminate. Strictly implement the process evaluation of welding deformation heat treatment standard and optimized parameter, to ensure the welding quality is better, more stable and reliable.
